Focal Power Performance (FPP) amplifiers give your music the clean, powerful boost it needs to sound its best. Their ultra-high frequency response reproduces all the harmonics and overtones that make vocals and instruments sound natural.

4-channel versatilityYou can use FPP 4100 4-channel amp to drive two sets of speakers with 75 watts RMS each, or you can bridge it to 2-channel mode to send up to 240 watts RMS each to a pair of subs for high-quality bass fill. In 3-channel mode, you can bridge the rear channels to power a sub with 240 watts, while still driving your front speakers with 75 watts each. Whatever role this amp plays, Focal power will give you superior performance for your system.

Superior designThe FPP 4100 sports a heavy aluminum chassis that disperses heat efficiently, so it runs cool even when you're pushing your system hard. This FPP amp also includes high-level inputs with signal-sensing, so you can hook one up to any receiver — even a factory stereo — without needing a separate turn-on lead. Focal includes a remote control that allows you to control your bass from the front seat.

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Focal FPP 4100

Excellent amplifier. I have been looking for a crisp, clean amplifier for my Z28 convertible and was recommended this unit by the Crutchfield advisor. Let me tell you.....This is awesome!!!!!! It makes my Focal speakers shine. The high are exceptional but not too bright, the mid-bass is fantastic. I am extremely impressed with this amp....You will be too.

High quality

I actually ended up returning the whole system as I was not satisfied by the sound quality and performance output. Because there are so many other components and factors, I am not sure of this amp was a contributing factor to the failure or not. So I am not sure what "star" rating to give it. It could have been many other things. I researched and tuned the system for a full week. Even though I spent a lot of money thinking I would get an extremely great sounding audio system, It did not sound all that much better than the factory bose system. At least not for what I paid.

SQ king, cannot beat it for the money!

If you are reading this, you are on the right track. Crutchfield has this amp specified with 75x4 at 4 while the box and manual rate the minimum power at 90x4 at 4. This amp is aimed to please anyone with SQ in mind and at 240 x 2 at 2, you even have enough power to run two decent size woofers. The frequency response from 80 hz+ on my Focal's is INCREDIBLE. I have owned quite a few amps in my day and this is HANDS DOWN the best 4-channel amp I have ever heard. The crossover and filters are amazing to only have a 12db/octave. All my frequencies slowly roll off and sound much more like 24db/octave. Moreover, the HPF and LPF are fairly sensitive, but once you get it tuned correctly, WOW. The way this amp brings frequencies together makes you feel like you are in a recording studio. You won't beat this amp for the money, Guarnteed!!

Features

Overview: The Focal Power Performance series amplifiers feature
a class-AB design for excellent sound quality. The aluminum chassis efficiently
dissipates heat to protect the amp from thermal overload. The compact size makes
the amp easier to install in tight places. The front-mounted connections and
top-mounted controls are easily accessible for a clean installation.

CEA-2006 Compliant: CEA-2006 is a new system of testing and
measurement methods for mobile audio amplifiers. This voluntary standard advocates
a uniform method for determining an amplifier's RMS power output and signal-to-noise
ratio. The criteria for measuring power uses a DC input voltage of 14.4 volts and
the RMS power output is measured into a 4-ohm load, with 1% or less Total Harmonic
Distortion (THD) plus noise, and at a frequency range of 20 Hz to 20,000 Hz (for
full range amplifiers). Signal-to-Noise ratio is measured in weighted absolute
decibels (dBA) at a reference of 1 watt into 4 ohms. CEA-2006 allows consumers
to compare car amplifiers and receivers on an equal basis. Following the CEA-2006
criteria, the FPP 4100 is rated at 75 Watts RMS x 4 channels with an 80dBA signal
to noise ratio.

2-Ohm Stable: When powering four speakers the amplifier is stable
down to 2-ohms. The amplifier is rated at 140 Watts RMS x 4 channels in 2 ohms.

Bridgeable: Either half (channels 1-2 and/or channels 3-4)
of the FPP 4100 can be bridged to one channel. If both sides are bridged, the
power output is 240 Watts x 2-channels into 4 ohms.

Top-mounted Controls: The amplifier has controls conveniently
mounted on the top panel under a removable cover. The controls include:

Gain Controls: independent rotary controls
for channels 1-2 and channels 3-4; continuously variable from 0.2
volts to 5.0 volts for the line level inputs and 0.4 volts to 9.0
volts for the speaker level inputs

Front-mounted Terminals: The FPP 4100 has all of its connections
on the front of the amplifier for a clean installation. The terminals include:

Speaker Outputs: four pair of set-screw
terminals for connecting speakers; they accept up to 10-gauge
wire; tightened/loosened with the supplied 2mm Allen wrench

External Remote: RJ-14 jack for use with
the included external remote control; the external remote
controls the output level of channels 3 and 4

Line Inputs: Left and right channel 1-2
and left and right channel 3-4 RCA jacks for the input signal
from the head unit

Hi Level Inputs: two 4-pin Molex jacks
for use with the supplied speaker level input harnesses

Fader: when only one set of inputs is
used (channels 1-2 and not channels 3-4), engaging the fader
button sends those inputs to channels 3-4 in addition to
channels 1-2

Fuses: the amp is protected by two 25-amp
ATO-type fuses; spare fuses are included with the amplifier

Power: two set-screw terminals for connecting
the power and ground cables; they can accept up to 3-gauge wire; a
4-gauge wiring kit is recommended for this amp; tightened/loosened
with the supplied 3mm Allen wrench

Remote: set screw terminal for the remote
turn-on lead; will accept up to 7-gauge wire; tightened/loosened
with the supplied 3mm Allen wrench

External Remote Control: The amp has an RJ-14 jack for use
with the included external wired remote control. The amplifier also includes a
15' cable to connect the remote to the amplifier. This remote allows you to
adjust the output level of channels 3-4 from your listening position. The remote
features a rotary knob and a power LED that illuminates when the amplifier is
powered on. The remote has two screw holes and can be mounted under the dash
(mounting screws not included). The wired remote dimensions are:

Width: 1-5/8"

Height: 1"

Depth: 1-3/4" (2-3/8" including
knob and wiring)

Auto Power On: When using the speaker level inputs, the Auto
Power On circuit senses an input signal and turns the amp on automatically. This
feature makes it easier to add an amplifier to a factory radio or to a receiver
with no preamp outputs.
